Abstract
A data acquisition circuit may isolate control and data decode logic elements from data acquisition elements such as sensors through the use of a single transformer. A control signal may be supplied to a primary winding of a transformer by alternately opening and closing a push switch and a pull switch. First and second analog to digital converter circuits may receive analog signals and convert them to data signals, which may appear on the secondary winding of the transformer. Data signals may be substantially received by a data demodulator circuit on the primary side of the data acquisition circuit. The data demodulator circuit may compare a voltage associated with the received signal to a threshold voltage and output a result of the comparison to the control and data decode logic element.
